Quite an assumption to make, and i'd question if anyone on this site has been "involved" with Linkin Park on any level besides listening to their music and going to gigs. Everything Linkin Park did after Meteora was a mix of generic, unimaginative or just plain bad. They had an amazing, unique sound with two brilliant vocalists playing off each other perfectly, but they changed into a band who lost all of what made them great.
Bands can evolve and change, some get better, some stay the same level, but with a different sound. Linkin Park? They just got worse. A lot worse.
